Sedimentary Rock
because magma are molten materials which exist below the solid rock of the earth's crust .we sedimentary rocks are formed by the result of deposition or accumulation and lithification of sediments of some weathered particles and other different materials therefore magma not often made because they don't contain fossils
Sedimentary rocks are made from particles called sediment. They are made from layers of sediment (small particles) on the bottom of rivers or seas. The sediments are compressed as more layers build on top of them. The particles then become cemented together to form solid rocks. The layers of rock are called strata. Sedimentary rocks have a grainy structure and they easily crumble.
Sedimentary rocks are formed from buildup of sediment, or particles of dirt and organic debris and things like that. Think of sedimentary rocks like the bottom of a river bed- stuff builds up on top until it becomes hard and solid- a rock, so pressure is a factor, but not necessarily heat. It is usually metamorphic rocks that involve both heat and pressure.
Cementation is the process of deposition of dissolved mineral components in the interstices of sediments. It is the sticking together of sediment to form a new rock and is an important factor in the consolidation of coarse-grained clastic sedimentary rocks such as sandstones, conglomerates, or breccias during diagenesis or lithification. Cementing materials may include carbonates, quartz, iron oxides, or clay. (Source wikipedia)

The process is known as Deposition.
The bonds between solid particles are weakened.
In geology, the term deposition refers to the settling out or placement of rock, particles of rock, or organic matter, generally referred to as sediments, after transportation by wind, water, ice, or gravity. Deposition occurs when the energy causing the transportation of sediments becomes unable to move the sediments any further due to its weight or friction with other particles. Deposition can occur in deltas, at the base of mountains, at the bottom of oceans, lakes, and seas, in sand dunes, or at the end of glaciers. The smaller the particle, generally, the further from its source will be its point of deposition.

# Weathering--the physical or chemical breakdown of rock into smaller particles. # Erosion--occurs when water, wind, ice, or gravity transport the rock particles. # Deposition-- the process by which sediment settles out of the water, wind, or ice carrying it. # Compaction- the process that presses sediments together, squeezing out air and fluids from spaces between particles. # Cementation- the process in which dissolved minerals crystalize and glue particles of sediment together. Note: it takes millions of years for compaction and cementation to transform loose sediments into solid sedimentary rock
The process is called deposition, where gas transforms directly into a solid without going through the liquid phase. This occurs when the temperature of the gas is lowered below its sublimation point, causing the particles to lose enough energy to form a solid state.
The gas can't generally turn straight into a solid, it has to change into a liquid and then a solid. When a gas turns into a liquid, the particles go closer together into groups and condensate. When the liquid turns into a solid, the particles all compress into a small space thus making a solid object.-----------------------------------------------------------------------But the phenomenon of change from a gas to a solid is also very known and is called deposition.
The expulsion of fluids which occupy the pore spaces in sediments gives way to the precipitation of solid minerals which bind the sedimentary particles together into rock.
